Point-in-Time Recovery (PITR) Backup and Restore
Pigsty uses pgBackRest to manage PostgreSQL backups, arguably the most powerful open-source backup tool in the ecosystem. It supports incremental/parallel backup and restore, encryption, MinIO/S3, and many other features. Pigsty configures backup functionality by default for each PGSQL cluster.
